Assessor Maps

Utilizing information received from government & subdivision maps, recorded deeds, road surveys, and other similar resources, the Assessor's office establishes and maintains a set of more than 21,000 maps delineating every parcel of land in the County. These maps serve as the basis for the assessment of all real property in the County of Riverside, and are continuously updated to reflect new subdivisions and parcels.

Copies of these maps as well as property characteristic information are available for purchase by the public. The maps include Assessor's parcel numbers, parcel & lot boundaries, recorded dimensions, acreage, street widths, adjoining parcels, and recorded map information. Street addresses and ownership are not shown on Assessor's maps, however, the Assessor's parcel can be used to obtain ownership and address information.

The per-copy fee for Assessor's maps is $6.50

You may obtain an Assessor's parcel map in person, at the County Administration Center in downtown Riverside, or in the mail by sending your request (along with your return address and a check or money order payable to "Riverside County Assessor") to:

Riverside County Assessor
P.O. Box 751
Riverside, CA 92502-0751
